Issue Do I need to purchase NPR's to put I/NET on the local network? Environment I/NET site Cause Do I need to purchase NPR's to put I/NET on the local network? Resolution Your local I/NET host(s) merely need to have NIC (network interface cards) installed and working. You will need to obtain properly assigned, static IP addresses from the network administrator. The only time you will need an NPR, is if you have controllers in stand alone mode, with Ethernet connecting them to I/NET hosts. If you do not wish to have a host near the controllers, you can situate an NPR to act as an Ethernet tap

Issue How to set momentary duration (pulse duration) on a 7780? Environment I/NET site Cause How to set momentary duration (pulse duration) on a 7780? Resolution Using a Hand Held Console: Press [Code], then type 07 and press [Enter] to set momentary duration. The current momentary duration in milliseconds displays. Enter the desired delay in milliseconds and press [Enter]. The range is 0-255 (0-2.55 seconds). For example, entering 100 from the HHC results in a one-second pulse to the relay to turn it On or Off. When using a standard 7780, the momentary duration value should be set to a minimum value of 10 (0.1 seconds).

Issue How to command all lights ON/OFF Environment I/NET site Cause How to command all lights ON/OFF Resolution Using a Hand Held Console Press [Code], then type 08 and press [Enter] to set All Lights On. The HHC display 0000. Type 1 and press [Enter] to enable All Lights On. To set All Lights Off, press [Code], then type 09 and press [Enter]. The HHC displays 0000. Type 1 and press [Enter] to enable All Lights Off. Side note: If code 08 and/or 09 have been used to enable the “All Lights On” and/or “All Lights Off” functions, input point addresses 0000 and 0001 will control the lights as desired. In the case, do not use these input points for any other hardware inputs. If these input points are used for other hardware inputs, the lighting circuits controlled by the 7780 DLCU will turn on/off unexpectedly.

Issue If a wink is attached to a circuit that is attached to more than one zone on which zone will it work? Environment I/NET site Cause Wink cycle attached to a circuit that is attached to more than one zone on which zone will it work? Resolution If you have a circuit attached to more than one zone with a wink cycle on it, the circuit will wink on the zone that turns off last. If you have a circuit attached to two zones and both zones turn off the lights at five, then the wink cycle will start at five.   If you have a circuit attached to two zones and one zone shuts off at five while the other zone shuts off at six, then the wink cycle will begin at six. One more example, is if the zone is set to two different zones and the zones are at different times. One is from seven to five and the other zone is on from eight to eleven, then the wink cycle will work at five then at eleven.

Issue If multiple circuits are on a zone and only one circuit has a wink cycle on it, will all the circuits wink Environment I/NET site Cause If multiple circuits are on a zone and only one circuit has a wink cycle on it, will all the circuits wink Resolution No, the circuit with the wink cycle attached to it will be affected by the wink cycle. The other circuits will shut down when the zone goes to off.

Issue The Analog inputs are reading too high or too low on a 7780. Product Line TAC INET Environment 7780 Cause Resistor configuration errors, damaged power supply, or the circuit may have been shorted. Resolution Several things could be contributing to this. Check the resistor configuration installed for the input and make sure it is correct. Check is the analog power supply (+15 VDC) has been damaged. Make sure a sensor does not have an open circuit in it (sensor is shorted).

Issue The Output relays will not control on a 7780, how can I fix this? Environment I/NET site Cause Output relays will not control on a 7780 Resolution First, check the matrix relay interface cable and make sure it is correctly connected. Secondly, make sure the matrix straps are not set incorrectly. Finally, Fuse F2 maybe blown. Fuse F2 is located near the top edge of the base card, directly above the LEDs. Fuse F2 is plugged into positions A and B of receptacle J20. This is a 0.5 amp pico fuse.

Issue Can I change a 7792 controller to a 7793 controller? Environment I/NET site Cause How to change a 7792 controller to a 7793 controller Resolution Yes, you can. However, you have to do a memory clear with a HHC (Hand Held Console). Once this is done, define the controller as a 7793.

Issue Site scheduled a special day and the output did not function correctly.  Environment I/NET site Cause Site scheduled a special day and the output did not function correctly.  Resolution If you have a special day defined in a DCU, there must be a special day schedule (S1 through  S7) defined for ALL the time schedules and controller points in the DCU. If a time schedule does not have a special day schedule defined, the point will remain at it last commanded state until the special day period is over.

Issue Extending a special days period beyond the end of a year Environment I/NET site Cause Extending a special days period beyond the end of a year Resolution Special days cannot extend beyond the end of a year. If you have a single holiday period beginning in December and extending into January, you must create two special day periods. One to cover the time in December and one to cover the time in January.

Issue What order of operation does the event sequence use? Environment I/NET site Cause What order of operation does the event sequence use? Resolution The event sequence runs in a linear manner. They must run from the first item in the sequence through to the last item in the sequence. Once started, the sequence must finish before it may be called again.

Issue Sub-LAN Connection in open loop operation: Environment I/NET site Cause Why is the Sub-LAN Connection in open loop operation suggested? Resolution Best Practice; It is recommended that if using the Sub-LAN in an open loop configuration that you jumper pin 1 to pin 4 and pin 2 to pin 5. This connects the primary and alternate ports. This is important because if the controller fails to receive a response from a Sub-LAN device on the first attempt it will try the secondary attempt on the alternate port. Connecting these ports allows you to have three attempts at communicating with the device rather then just two.

Issue Use controller addresses to assist in identification of wiring problems in an I/NET controller LAN. Environment I/NET site Cause How to use controller addresses to assist in identification of wiring problems in an I/NET controller LAN Resolution It is common to find installations where the controller addresses follow the physical layout of the wire. This allows the token to be passed between nodes which are closest to each other on the controller LAN. When the controllers on the opposite ends of your controller LAN have consecutive addresses this will require the token to pass the entire length of your controller LAN between those two controllers. (This includes when the token passes between the highest node address and the first if the network addresses are assigned sequentially.) The advantage of this setup is that many communication problems can be identified quickly while your installation technicians are still on site and thus avoiding a return trip when other (new) conditions have degraded the performance of the network.

Issue How do you change the default colors applied to the value of points placed on a graphics page? Environment I/NET Site Cause How does one change the default colors on a graphics page? Resolution Go into the graphic properties editor and choose one of the following: Text Pen - Use this option to choose a default foreground color for point text. When you select this option the system displays the color dialog. You can choose a standard system color or you can define a custom color. This setting will be ignored if you have activated the Use Object Pen option described below. Use Object Pen - When activated this option causes the default color for point values to be the color defined within the points font properties. Otherwise point values are displayed in the color you choose using the Text Pen option described above. The Use Object Pen settings do not affect the color of text objects or markers. It also has no affect on points that have already been placed on the graphic page.

Issue I/NET Seven does not support the 7791/7792 MCI platforms. Only the 7793 MCI platform is supported. Consequently, a conversion from the 7791/7792 MCI platforms to the 7793 MCI platform is necessary. The following steps should insure a correct conversion. Environment 7791/7792 MCI platforms Cause I/NET Seven does not support the 7791/7792 MCI platforms. Only the 7793 MCI platform is supported. Resolution A Hand Held Console (HHC) is required for this process. Turn EVERY sub-LAN device “Internal” using the MCU Configuration Editor under Edit > Controller > MCU Configuration. Save the current databases in the MCIs (7791/7792). Attach the Hand Held Console (HHC) to a MCI. Use the following keystrokes to clear the MCI memory: CTRL, MEM, ENTER, “0”, ENTER. Press the red RESET button on the MCI The indication on the HHC should be seconds counting up from zero. Using the HHC, enter CODE, 90, and press the ENTER key.  The display should show the current MCI configuration (i.e., 7791 or 7792 and TAP emulation of 01, 03 or 06).  Using the increment/decrement keys advance the display to show 779301 or 779306 (use the –06 if dialing into a MCI with the RS-232 Expansion board attached--otherwise use the -01) and press the ENTER key.  The display should indicate seconds counting up from zero.  Check the COMM port speed on the MCI using the HHC.  Enter in CODE, 91, and press the ENTER key.  The display will show the COMM port speed, typically 19,200 if directly connected to a PC.  Change the port speed using the INC key to 19200 if necessary. Move the I/NET 2000 saved databases (DCUXXXX.sav) to the SAV folder in I/NET Seven. In I/NET Seven connect to the Link address where the MCI is located.  Go to Edit > Host Computer > Software Restore, and check the MCI address to download the .BIN file only (do not load the .SAV file here).  After the .BIN file downloads to the 7793, connect to the MCI.  Go to Edit > Controller > Station Restore, and download the .SAV file to the controller.

Issue Upgrading a File Master I/NET Seven Software from revision 1.10 through Revision 1.xx. Environment I/NET site Cause Possible problems with upgrading from I/NET 1.10 to 1.16 Resolution There are some issues that users are running into when they upgrade their software over the Internet from earlier versions of I/NET Seven revision 1.10 through revision 1.16. Most commonly is that Equalization does not work and error messages are generated during the promotion of the Clients to the File Master. The following steps should be taken to avoid these problems: If Upgrading from I/NET 1.10 to 1.16, all the upgrades need to be done i.e. 1.10 to 1.12 to 1.14 to 1.15 and finally 1.16. On the File Master go to the DB Create Utility and force an upgrade on the database. A message comes up saying that you are set up as the File Master, do you want to drop Equalization. Select Yes, this will allow the user to drop all the clients that are connected to it. Start I/NET again and let the File Master re-promote itself. Once finished, open I/O Server, modify the active profile and uncheck the file master box. Once it becomes a Stand Alone Host again, close down I/O Server and shut down I/NET. Restart I/NET and follow step 3, this time check the box to promote Equalization again. This time you’ll get a box to enter a Password only, create a new Password. Upgrade the Clients Software and repeat step 3, removing the File Mater name from the box. Follow steps 4 and 5 and the user can put either the PC name or IP address of the File Master here. Once it receives the Snapshot from the File Master, verify that Equalization is taking place by comparing the databases, or make a change and verify that is was replicated. Now bring up all the remaining Clients by following steps 6 and 7.

Issue I/NET Seven DPU 7920 48K features list. Environment I/NET Cause What are the I/NET Seven DPU 7920 48K features Resolution Features: Secondary schedule. Shift management. Expanded elevator control to support up to 79 floors. Notes: To use any of these features requires that the DPU be a 7920 with a MIP board. 7910 and 7920 without a MIP board will work with the I/NET system but they cannot use these functions.  The host prevents the download of these features to any DPU revision prior to 3.10. Please check the compatibility matrix associated with your I/NET Seven software Bin file revision.

Issue NPRs - Solution information for IT professionals. Environment I/NET site with a network Cause Is there information for the site IT Professional concerning NPRs Resolution The I/NET control network, on which the NPR is a component, makes exclusive use of UDP/IP packets. All retry, the control network applications layer handles timeout, and other packet transfer reliability. The maximum packet data component size is 140 bytes. The maximum UDP/IP packet size, including MAC and IP headers, is 186 bytes. Most control network transactions occur in the following four sets of packets: Transmission packet, Acknowledge packet, Response packet, and Response-Acknowledge packet. This is true for all transaction types including manual operator control actions initiated from I/NET, controller software downloads, and trend data uploads. Three control network packet transaction types occur periodically and are formed as a set of two packets. These transactions are for node to node (on the control network) supervision, global data point distribution, and message (alarms, transactions) distribution. This two-packet set is constructed of a Transmission packet and a Response packet. Node-to-node supervision occurs every 15 seconds. Global data point and message distribution occur at random intervals depending on the operator settings for those events on the control network. Acknowledge and Response-Acknowledge packets are 64 bytes in length. Transmission and Response packets will vary in length from 64 bytes to 186 bytes. The data content of the UDP packets is proprietary to TAC control networks. Critical configuration packet transactions between TAC control network machines use private key encryption to protect the data content. All other packet data contents are not encrypted. The highest Ethernet network utilization will occur during an I/NET host PC to NPR software restore action. This is the only sustained network activity where transmission packet sizes are filled to the maximum of 186 bytes. It is also the only control network activity that will generate a continuous transmission data stream. Network utilization during activity will be between 2 and 3 percent. To validate this statement, the Triticom Landecoder32 Ethernet monitor was used to observe network activity during the software restore process. Broadcast UDP/IP packets are NOT utilized by the control network applications. The only Ethernet broadcasts that will be used are standard ARP broadcasts for normal MAC to IP address resolution. The NPR requires a static IP address assignment. The control network makes use of logical port number 50069 as the transmission packet destination. The NPR exposes an SNMP agent that will provide SNMP managers access to the standard MIB2 network variable set. The NPR exposes a limited Telnet service that provides connecting clients access to control network specific debug information such as the application layer routing table a well as the IP stack routing table and ARP cache. The NPR operates at 10 Mbs and communicates at half duplex.  

Issue Client Button Feature for Equalization Environment I/NET site Cause Is there a button available to users who are utilizing the Equalization Feature of I/NET? Resolution There is a new button available to users who are utilizing the Equalization Feature of I/NET. This button allows the user to see when the Clients were contacted last by the File Master and makes Trouble shooting easier. The following shows how it should be set up and used: In the I/O Configuration, open the active profile (the one being used for Equalization on the File Master). Click on the Equalization File Master check box. Once Equalization has been set up and the Clients are on line, follow step 1 again. Click on the Clients Button, which is now active, a list of the Clients will show up. The user can now see the last time a Client was polled and it can be dropped by selecting it and clicking Drop.

Issue Configuring Filters in AMT For I/NET Seven rev 1.15 and later. Environment I/NET Seven rev 1.15 and later AMT Cause I/Net Seven Revision 1.15 and later releases the default Windows for AMT can no longer be filtered and the Icon is grayed out. Instead, there are two buttons on the Task bar for Alarms and Events that can be used for filtering once selected. Resolution The following steps should be followed to set these up: For Alarms, Select the Alarms Button, this creates a new window and the user can set what types of options they want to be displayed. The Icon is now available and the user can filter accordingly. For Events, Select the Events Button, this creates a new window and the user can set what types of options they want to be displayed. The Icon is now available and the user can filter accordingly. Note: If the user is creating a window for Critical Alarms to filter on, they should not open the default window because it causes AMT to populate two sets of windows and in turn use up necessary resources.
